Novel bisbenzimidazoles with antileishmanial effectiveness

A small library of 2,2′-[(α,ω-alkanediylbis(oxyphenylene)]bis-1H-benzimidazoles has been prepared and screened in vitro against Pneumocystis carinii, Trypanosoma brucei rhodesiense, and Leishmania donovani. Among the six tested compounds two derivatives emerged as promising hits characterized by IC50 values lower than that determined for pentamidine against L. donovani.

The synthesis and pharmacological profile of novel bisbenzimidazoles is reported.Figure optionsDownload as PowerPoint slide
